When we are making a song for Billie I want it to resonate and speak the truth with her and want it to be a piece of fabric she can wear.

The excuse of having a dog is great, because before I had a dog, I wouldn't be like, 'I need to go hike for two hours'; my girlfriend would have been like, 'What are you doing?' Now I take the dog, and she comes with me.

You know, I grew up very self-taught.

I love pop songs so much and I don't put a ton of pressure on myself as a solo artist to always write the most commercial feeling thing, I just want to write things I would love to listen to.

My feeling is that everybody starts out as an emulator. You follow their approach and that's how learning works. The pivot is that I don't think you're going to break new ground unless you do something different.

I was on a TV show called 'Glee.' I mean, I was on the real tail end of that show; it was already way past its peak. But still, for me aged 17 landing something like that was a big deal.

In my perfect world, I get to be a professional musician and still go to Trader Joe's.

I think the whole response to our art being so positive is that it rings true and it feels a unique thing and I feel that was the thing that we strive for in the beginning was to not conform to any preconceived notions of what we should be doing.

It's always important to be checking in with people you love.

Kids have tools to do what I'm doing.

I think that, for us, the thing that no one can take away from you is that if you make something that they've never heard before, they're gonna respond to that. They may not love it, it may not be their favourite thing, but no one can take different from you.

I really value just being able to go out and grab a coffee or going to a movie and not have anyone recognize me.

To me, my favorite joke on a stand-up special is when someone says something and you go, 'Oh my God, I've been thinking that my whole life, I've just never said it to anyone else.' Those little kinda quiet, personal observations you make that nobody else has talked about yet.

I'm not an author, but as a songwriter, I'm afforded this kind of luxurious ambiguity in songs of being able to confess the secrets of my relationships with people and face basically no consequences, or ask for no approval or permission.

For me, I'm going to try to make my favorite song over the most popular song.

Everybody has different taste and everyone's favourite song is different and that's great.

I came to NAMM once and saw this guitar that self-tuned, and I thought, 'Wow, this is the future!' And I've never seen it again.

I idolize my kid sister, so I get it. I understand why other people do too.

I don't analyze songs because I think it will make me a better songwriter, I just do it out of sheer curiosity.

What I really didn't want to do is work with other people and have them go, 'Oh, Finneas just does that sound for everybody.' The Billie sound is only Billie - I'll only do that for her.

I mainly try to foster long-term collaborative relationships.

There's no other person I like working with as much as my sister.

I think if you're not trying to change things a little bit, you're not evolving.

If I'm making a song with Billie, then it's for Billie... She has to want to wear that song every day. And I think I try to do the same thing when I'm making a song for myself... I try to treat them both that way, like I'm sort of A&R-ing her and then A&R-ing myself.
